Version 2.0 of the USB4 standard, which retains cable backward compatibility while doubling transfer speeds over the previous standard, has now been formally released by the USB Promoter Group. That is based on recent reports after a declaration from the group.
Backward compatibility is a given for USB Type-C cables that support USB4 version 2.0. This means that they will continue to function with previous USB Type-C ports including USB4 1.0, USB 3.2, USB 2.0, and Thunderbolt 3. The USB4 Version 2.0 ports will also handle earlier USB Type-C cables. Nevertheless, lacks the quickness demanded by the new standard.
WHAT ELSE DOES USB4 VERSION 2.0 BRING TO THE TABLE APART FROM BEING TWICE AS FAST AND JUST HOW FAST IS IT? In addition to being compatible with those most recent versions of DisplayPort and PCIe, the new standard is specifically designed to be compatible with them as well. As a result, the new standard’s utility as opposed to earlier versions is undoubtedly increased.
Advertisement But the speed itself, which will enable considerably more robust use-case scenarios, will undoubtedly be the main news here. Having a laptop’s ability to connect to external graphics cards is one example.
This is so that data can be transferred at up to 80 Gbps using USB4 version 2.0. It is therefore an almost ideal protocol for many different use scenarios. Whether that be for hubs, docks, high-end monitors and displays, external or internal storage devices, or other accessories. or a variety of other situations.
Now, this doesn’t represent the complete set of new capabilities or enhancements that USB4 version 2.0 will provide. As is frequently the case, additional information about the new protocol will become available as time goes on. November 1 is the next scheduled day for the disclosure of information. Particularly around the USB Developer Days conference in 2022. As of this writing, it is unclear what more information USB Promoter Group has to share regarding the technology.
